-- The question doesn't specify the type of device where this cathode is found.
I have to assume ... since a range is specified for the assumed wavelength of
visible light, and because the question is posted to the < Visible Light > category ...
that we're dealing here with a device designed to detect visible light, such as a
photodiode.
-- The photons with the greatest energy will be those corresponding to the highest
frequency/shortest wavelength ... 390 nm .
-- 1 Joule = 6.24 x 1018 eV
-- So the cathode work function must be
hc/λ = (6.63 x 10-34) x (3 x 108) x (6.24 x 1018)/390 x 10-9 = 3.18 eV
or less, in order for the circuit to respond to visible light.
This number sounds quite reasonable for the process we're discussing here,
so I'm just going to leave it like that and quietly tip-toe out of the room.
The work output of a Carnot engine would be the maximum possible, i.e. it would yield the maximum possible efficiency for conversion of input energy into useful work.
Maximum entropy is when thermal equilibrium is reached and no further vaporisation is possible.

Addition is the maximum or minimum function in math.
By taking the derivative of the function. At the maximum or minimum of a function, the derivative is zero, or doesn't exist. And end-point of the domain where the function is defined may also be a maximum or minimum.
Maximum possible vacuum is -0.1 Mpa
The minimum is the vertex which in this case is 0,0 or the origin. There isn't a maximum.....
Cathode (electron) rays have less ionizing potential than gamma, beta, and alpha rays (in increasing ionization potential).

The "maximum" function.
It depends on the function whose maximum you are trying to find. If it is a well behaved function over the domain in question, you could differentiate it and set its derivative equal to 0. Solve the resulting equation for possible stationary points. Evaluate the second derivative at these points and, if that is negative, you have a maximum. If the second derivative is also 0, then you have to go to higher derivatives (if they exist). If the function is not differentiable, you may have a more difficult task at hand.
If x is the unknown or variable in an equation it can have many possible maximum or minimum values
therapy can be helpful with positioning devices and strategies for accomplishing daily tasks. Physical therapists can assist with exercises to help maintain maximum possible range of motion
Both the function "cos x" and the function "sin x" have a maximum value of 1, and a minimum value of -1.
Find the maximum and minimum values that the function can take over all the values in the domain for the input. The range is the maximum minus the minimum.
